摘要
分析了ARM7TDMI的结构特点,根据处理器结构对MPEG-4编码算法进行了优化。通过采用双BlockDCT、优化的VLC编码及NGDS运动估计算法等方法,大幅度提高了编码器的速度,达到实时编码的要求。
After analyzing the architecture of ARM7TDMI,MPEG-4's algorithms are optimized,By used methods of two Block's DCT,optimized VLC and NGDS motion estimation,the encoder's speed is prompted,and real-time encoder is realized.
